JACOB NESSLY PORTER, OF KENILWORTH, WEST VIRGINIA, ASSIGNOR TOTHE GLOBEBRICK COMPANY, OF EAST LIVERPOOL, OHIO, .A. CORPORATION OF WEST VIRGINIABRICK MACHINE Application filed December 9, 1929. Serial No. 412,829.

This invention relates to a brick press, more particularly to anattachment therefor actuated by the pressing mechanism for feeding thebricks away from the pressing position.

In machines for pressing bricks, of which I have knowledge, each brickafter it is molded, shaped or pressed, is fed from-the pressing positionforwardly by a reciprocat ing member of the machine, and such brick inturn engages and feeds forwardly the previously formed brick or bricksdepending upon the length of the feed table or the speed at which thedelivered bricks are removed therefrom. Due to the forcerequired to moveor feed the bricks along the table, contact of one brick with anotherfrequently results in damaging their surfaces or marginal edge portions.Also, portions of the brick dust and the brick material, whichaccumulate on the feed table collects in front ofeach brick as it ispushed forward by the reciprocating member into engagement with thepreceding brick, with the result that this collected material iscompressed between such brick and the next forward brick as both bricksfeed forwardly. This compressed dust or material usually adheres to one,brick or the other or usually result in seriously damaging them as theprojections when removed invariably carry with them portions of thebrick body,

this being particularly true since the material adheres to the surfacesof the bricks near and along their lower edges and the edges break awaywith the projections relatively easy.

One object of the invention is to provide an improved attachment for abrick press ca pable of feeding bricks forwardly, after molding orshaping, in spaced relation,

whereby contact of the bricksone with another While being fed forwardand collect-- ing and compression of free material between the brickswith resulting adhesion thereof to Another object of the invention is toprovide in a brick press an improved supplementary feeding devicearranged to co-operate with the main delivery or feed member of thepress to maintain the bricks during feeding in spaced relation.

Another object of the invention is to provide an improved auxiliaryfeeding attachment fora brick press correlated with the deliverymemberthereof and capable of adjustment for feeding bricks of differentsizes.

A further object of the invention is to provide an auxiliary feedingdevice for a brick press which is relatively simple in construction andreadily attached to the press'mechanism for feeding bricks of varyingsizes.

Other objects of the invention will be apparent to those skilled in theart to which my invention relates from the following description takenin connection with the accompanying drawings,.wherein Fig. 1 is'asectional View of a brick press embodying my invention, the pressingmechanism being shown'in the position it occupies when pressing thematerial into a brick.

I My invention is applicable tobrick making adapted in its forward movement to move machines having areciprocatable member 7 each brick or series of bricks away from theshaping, pressing or molding position. One such machine is shown in thedrawings and may be briefly described as follows:

1 indicates a suitable support for a frame 2.

The frame 2 comprises spaced side members 7 20 (one only being shown)hollow members 26, 2b, to which the side and transverse 7 members 2a arerigidly connected. The transverse members 25, 2?) rest on the support 1.Each side member 2a is shaped along its front portion to form an innerend wall 3, which co-operates with an outer removable end wall 4 to forma vertical guide 5, the guide on one side member 2a together with asimilar guide on the other side member slidably supporting pairs ofupper and lower shoes 6, 7, the purpose of which will later ap pear. edin bearings 9 provided 011 the side members 2a, the shaft having on oneend a pulley 8a or other device to receive power from a suitable drivingmeans. The pulley 864 may be connected to and disconnected from theshaft 8 by means of a suitable clutch 8. At its other 'end the shaft 8is drivingly connected through gearing (not shown) with a countershaft10, supported similarly to the shaft 8, and the counter-shaft 10 in turncarries a pinion 11 meshing with a gear 12. The gear 12 is fixed to ashaft 13 suitably mounted in the adjacent side member 2a. On its innerside but outwardly of the side member 2a, the gear 12 carries a castingshaped to form a continuous camway 14:, the purpose of which Will laterappear. The shaft 13 at its inner end is provided witha crank 15 to theend of which is pivotally con nected the inner end of a combined thrustand rocking member 16. The outer end of the member 16 is pivotallyconnected to a pin 17, which pivotal ly connects the inner ends of aplurality of toggles each comprising links 1819 (one toggle only beingshown). The outer ends of the links 1819 are pivotally mounted on crossshafts 20, 21, respectively supported rotatively at their opposite endsin the pairs of shoes 6, 7, respectively.

The combined thrust and rocking member 16 is adapted to roll on a roller22 loosely mounted on a stud shaft carried by the adjacent side member2a, this roller being so related to the shaft 13 that the crank 15 inco-,

operation therewith causes the outer end of the member 16 to traverse apredetermined cycle in each revolution of the crank 15, the effect ofwhich through the toggles is to move the shoes upwardly or downwardlyand relative to each other to produce in each such cycle a brick orseriesof bricks in the manner pressers 24, 25, one pairfor each opening,

connected to and operated by the shoes 6, 7,

to press the bricks. The forward portion of the base a co-operates witha shelf 26 to form a feed table 26 for the bricks A and the innerportion of the base and a cross plate 27, suitably supported by the sidemembers .8 indicates a main drive shaft mount 2a, provide a surface onwhich a member 28 reciprocates, this member being guided in itsmovements by suitable guides 29 at the opposite side edges of the crossplate 27. By preference the base 20a and cross plate 27 are covered witha steel plate 27a to provide a plane, jointless surface for the member28 to slide on. The reciprocating member 28 is shaped to form fourpockets 30 and a gate 31 rearward thereof; and in the rearmost positionof the member 28 (see Fig. 2) these pockets register with the deliveryopenings of a supply hopper 32 to receive suitable brick material Btherefrom and in its foremost position these pockets register with thedie openings 23 and permit the brick material B to flow into the latter(see Fig. In this latter position, the gate 31 moves below the hopperopenings to close them. The reciprocating member 28 has a movementslightly longer than the length of the bricks measured in the directionin which the member moves and is operated in timed relation to themovements of the pressers 24, 25, by the following elements: 33indicates a pitman connecting the rear portion of the member 28 with thefree end of an arm 34:. The arm 34% is fixed to one end of a rock shaft35 suitably mounted in the adjacent side member 2a; The other end of theshaft 35 carries a crank 36 having a stud 36a which retatably supports aroller 37 adapted to ride in the camway 14, the latter being shaped toeffect reciprocating movements and rests therebetween for the member 28.

The presser 24: is carried by a base portion 38 which is guided in itsup and down movements by opposing guide walls 39 provided interiorly ofthe transverse member 2?). The opposite ends of the base portion areconnected to the lower ends of a pair of plungers 40 connected at theirupper ends to the opposite ends of the shaft 20 outwardly of the shoes6, the plungers serving to support the base portion 38 and presser 24and to move the latter upwardly and downwardly with the shoes. Thepresser 25 extends between and is connected to the shoes 7 and movestherewith upwardly and d wnwardly.

' In the cycle of movements of the outer end of the member 16transmitted through the toggles to the shoes 6, 7, the pressers 2 25,are separated as shown in Fig. 3, at which time the reciprocating memberis in its forwardmost. position and registering with the dies to fillthe latter with the brick forming material B. In the movement of thereciprocating member 28 to this position its front wall 2860 has engagedand moved the previously formed bricks A forwardly on the table 26;next, the member 28 moves rearwardly and the presser-s are moved intopressing position in the dies as shown in Fig, 1; next, the pressures24-, 25, move upwardly, the presser 292 carrying the pressed bricks ill;

upwardly to the plane of the table 26 (see Fig. 2) the movement of thepresser 25 being accelerated relative to that of the presser 24; andnext, the reciprocating member 28 moves forward to move the pressedbricks forwardly and to refill the dies.

41 indicates an auxiliary feeder, arranged to move with thereciprocating member but in spaced relation therefrom. The feeder maycomprise a single device or a plurality of devices disposed in front ofthe reciprocating member 28 and spaced therefrom a distance greater thanthe length of a brick but less than the distance between it and the rearsurfaces of the bricks when in the position to which they are moved bythe member 28. In the preferred form of construction I provide twofeeders 42, 42, each common to two bricks and connect each thereof by anarm 48 to the reciprocating member 28. The arm 43 may be of sectionalform having overlapping portions clamped together in adjusted relationby one or more bolts 44 extending through elongated slots 44a formed inthe sections so that the feeder 42 carried at the outer end of the outersection maybe adjusted different distances from the reciprocating member28 according to the length of the bricks A. The inner end of the innersection is preferably bent downwardly as shown at 45 and formed with anelongated slot 45a, bolts 46 extending through the slot to adjustablysecure the end 45 to the front wall 28a. The adjustable connectionpermits the arm to be raised or lowered and thus adjust, the-feeder tobricks of difi'erent heights. Each arm end 45 is connected to the frontwall 28a midway between adjoining bricks A and the adjacent arm extendsforward therefrom in the plane of the space between the bricks. Theadjacent feeder 42 is hingedly connected to the outer end of the arm anddepends therefrom and extends to either side of the arm so as to engagetwo of the previously formed bricks in the next forward movement of thereciprocating member 28. (See Figs. 2, 4 and 6.)

As this latter movement takes place, the previously formed brlcks willbe moved forwardly, but maintained out ofcontact with the bricks beingsimultaneously moved forwardly by the reciprocating member 28, as shownin Fig. 3. By hinging the feeder 42 on the arm, its lower end is free toswing outwardly, so that, in its rearward movement it will ride thebricks moved forwardly by the reciprocating member (see Fig. 5) to aposition rearwardly thereof (see Fig. 2) ready to engage them in itsnext forward movement. The free end of the outer arm section may be bentdownwardly, as shown at 47 to form an From the foregoing description itwill be noted that each series of bricks after being formed are fedforwardly from the forming or shaping position by the reciprocatingmemher and in the next movementthereof the auxlliary feeder moves themoutwardly on the table while the next or succeeding series of bricks isbeing moved by the reciprocating member. By positioning the feeder inspaced relation to the reciprocating member as herein described, thebricks fed by it are maintained in separated relation to those being fedby the reciprocating with the result that the bricks cannot contact onewith another and any free material which collects in front of themcannotbe compressed between and against their front and rear surfaces.

To those skilled in the art to which my in vention relates many changesin construction and widely differing'embodiments and applications of theinvention will suggest themselves without departing from the spirit andscope thereof. My disclosures and the description herein are purelyillustrative and are not intended to be in any sense limiting.
